Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention provides for the footrest to be disposed in front of the seat and continuous with the seat when necessary, and to be completely stored under the seat when not required. Concerning possible chairs with footrests.

B. Prior art When sitting in a chair in a relaxed state, it is easier to raise your feet to the same height as the seat than to sit with your feet on the floor, even though it may be considered a bit of bad manners. Therefore, from the past, for example,
As described in Publication No. 150638, bus seats are equipped with a footrest at the rear lower part of the front seat that can be set to the foot rest position by pulling down, and The footrest housed in the seat can be pulled out to the front of the seat and placed in a continuous manner with the seat, or as described in Japanese Utility Model Application Publication No. 179732/1983,
Some have a footrest that slides parallel to the bottom of the seat and flips over when it protrudes toward the front of the seat.

C. Problems to be Solved by the Invention Among the conventional chairs with footrests, the first one can only be used as a footrest on a bus seat, and a general chair alone does not function as a footrest. In the second case, the setting work of the footrest is complicated, and it does not look good when stored. In addition, in the third case, the footrest was supported by a sliding operation that protruded toward the front of the seat, so the footrest could not be made larger, and it was small and gave the impression that it was an accessory. . Furthermore, not only do these chairs have a poor footrest effect, making it difficult to relax, but the space under the seat is not effectively used as a storage area for the footrest, so when the footrest is stowed, the chair as a whole looks bad.

D. Means for Solving the Problems Therefore, the present invention makes effective use of the space under the seat as a storage area for the footrest, secures a sufficient size for the footrest itself, and allows for easy setting by just pulling out the seat. This provides a chair with a footrest that has a sufficient foot rest effect and a functional aesthetic design, and its configuration is such that a slide rail is provided on the back of the seat in the front and back direction, and the chair can be slid in the longitudinal direction on the slide rail. combining a sliding body, one end of the connecting member is pivotally supported on the sliding body,
By pivoting the other end of the connecting member to the rear end of a footrest that can be stored in the space under the seat with the supporting legs fixed to the front lower part, the footrest can be moved between the bottom of the seat and the front of the seat. When the footrest is moved and pulled out to the front of the seat, the pivot portions at both ends of the connecting member rotate to allow the rear end of the footrest to be lifted up to the seat height, and the footrest is extended continuously toward the front of the seat. The reason is that a fixing mechanism is provided for fixing the device in the forward and downward position.

E. Function When the footrest is accommodated, the footrest is housed in a well-balanced manner by effectively utilizing the space under the seat. When the footrest is pulled forward, it first slides forward, and then the connecting member rotates. It can be easily set up by a series of movements in which the rear end is raised and fixed once it reaches the height of the seat. Since it is set in a forward tilted position, it has an excellent foot rest effect.

Embodiment Next, in order to concretely explain the structure and effects of the present invention, an embodiment of the present invention will be explained based on the drawings as follows.

In FIG. 1, reference numeral 1 denotes a seat, and slide rails 2, 2 each having a square cross section are arranged on both sides of the back side of the seat 1 in the front and rear direction.
sliding bodies 3, 3 each having a square cross section are inserted into the
Connecting rods 4, 4 are rotatably supported on the sliding bodies 3, 3. Since both sides of the back side of the seat 1 have the same structure, only one side will be described below. The sliding body 3 can move freely within the slide rail 2,
Attachment plates 2a, 2a are provided protrudingly below.
On the other hand, one end of the connecting rod 4 has a connecting member 4 having a U-shaped cross section.
a is attached, and the mounting plates 2a, 2a
In between, a connecting member 4a attached to one end of the connecting rod 4 made of a U-shaped pipe is connected by passing the pivot pin 4b through the mounting plate 2a, the connecting member 4a, and the mounting plate 2a in this order. A connecting rod 4 is rotatably supported. Connecting rod 4 on one side of the pivot
It is equipped with a fixing mechanism that fixes it in a predetermined position.
The fixing mechanism includes a hollow pyramid-like structure in which one side of the mounting plate 2a extends downward, an insertion hole 5a is bored in the extension part 2'a, and an insertion hole 6a is formed in the outer surface of the fixing mechanism. A bracket 6 is attached, and both insertion holes 5 are attached.
A lock pin 7 is inserted through holes a and 6a. An inward biasing force is applied to the lock pin 7 within the bracket 6 by a pin 5b and a spring 5c, and a fixing hole (described later) is bored on the side of the connecting rod 4 in the direction of the biasing force. By inserting the lock pin 7 into the fixing hole, the pivot portion can be fixed. Reference numeral 8 denotes a footrest, and the footrest 8 has a short leg 8b protruding from the lower front side of the cushion portion 8a, which allows the footrest 8 to slip under the seat, and a short leg 8b protruding downward from the lower rear side. The two mounting plates 9a, 9
A mounting bracket 9 consisting of b is attached. The other end of the aforementioned connecting rod 4 is rotatably supported on the mounting bracket 9 by a pivot pin 4'b via a connecting member 4'a attached to the other end of the connecting rod 4. hand,
The footrest 8 can be stored in a space under the seat in a connected state via the sliding body 3 and the connecting rod 4. At the pivot point between the sliding body 3 and the connecting rod 4, a fixing hole 10 is provided on the side of the connecting rod 4 at a position where the tip of the lock pin abuts when the footrest is in the retracted position and when the footrest is pulled out and the rear end is lifted. , 11 are drilled in the footrest, and it is possible to pull it out forward with the footrest fixed in the stowed position, but if you release it before pulling out the footrest, the rear end of the pulled out footrest will be It can also be fixed in the lifted position. To release the fixation, press lock pin 7
Remove the lock pin 7 from the fixing hole 10 (or 11) by pulling it outward, and rotate the connecting rod to remove the lock pin 7 from the fixing hole 10 (or 11).
1) may be shifted. When the locking pin 7 is released, the tip of the locking pin 7 moves while being pressed against the guide plate 12 fixed between the fixing holes 10 and 11 by the spring force, and does not rotate during that time. It becomes a state of freedom. In the drawing, the reinforcing pipe 13 installed between the connecting rods 4, 4 firmly connects the left and right connecting rods, moves them together, and prevents the footrest from collapsing when the footrest is moved in and out. are doing.

It is also possible to support each pivot without attaching the connecting members 4a, 4'a, each having a U-shaped cross section, to the end of the connecting rod, but in that case, other fixing mechanisms may be attached to the pivot. It is necessary to provide

The chair with a footrest configured as described above can be stored in the space under the seat when the footrest is unnecessary. In that case, the footrest can be completely stored deep under the seat, so even if you sit with your legs bent at right angles, your calves and heels will not come into contact with the footrest, and you can use it just like a normal chair. When using the footrest, when you pull the footrest forward from under the seat, the footrest will first protrude to the front of the seat, and then the rear end will be lifted up by the rotation of the connecting rod, making it continuous with the seat. Become. When the footrest is in a continuous state toward the front of the seat, the fastening hole matches the position of the locking pin, and the tip of the locking pin is inserted into the other fastening hole by the force of the spring, thereby fixing the sliding body and the connecting rod. . The footrest is thereby supported by the front legs and the rear connecting rod and set in position. In this setting state, the footrest is continuous with the seat, and since the legs 8b are short, they are lowered forward, providing a great foot rest. In the chair with a footrest of the present invention, when the footrest is pulled out forward, the sliding body follows the slide rail and the leg body slides on the floor surface, so it can be done smoothly, and when the footrest is pulled out, the rear end of the footrest is lifted. In some cases, when the connecting rod connecting the seat and footrest rotates, the movement is a continuous series of movements until the footrest is set in place, and in the setting state the two are one body. It doesn't feel unnatural, like it's been made into something.

In the chair with a footrest of this embodiment, since the connecting rod as a connecting member is formed in a U-shape, it matches the movement of the footrest and makes an arcuate movement when rotating, giving it a beautiful and mobile appearance.

In the present invention, the slide rail and the sliding body are a combination in which the sliding body can move in the sliding direction, so that the sliding body is not only fitted into the rail but also fitted outside the slide rail or attached to the wheel. It can also be attached to ensure smooth movement. Also, the connecting member is not limited to a U-shape,
By using a link with an appropriate fixing mechanism or by using a plate pivotally supported by a hinge member that exerts a snapping force on both bent sides, the rear end of the footrest is constructed so that when the footrest is pulled out, the snapping force causes the rear end of the footrest to fly up. However, the fixing mechanism is not limited to the mechanism shown in the above embodiment depending on the structure of the pivot portion.

G. Effect The chair with a footrest of the present invention effectively utilizes the wide space under the seat as a storage area, so the footrest can be made larger, and when set up, it becomes continuous and integrated with the seat, which improves the design. Also excellent. Furthermore, since the footrest is set forward and downward due to the combined action of sliding and rotation, it has excellent operability and allows the user to take an ideal resting position from an ergonomic point of view, since the calves are in contact with the footrest.
